I was just playing around the website, and saw the 4 buttons at the bottom of the site; as I have many times. Only this time, I decided to actually check where they they you, as I've seen similar webs use this as a sort of verifyer of whatever they have.
The 2 ones content "only" information and the link to the 2 on the right suggest they are indeed some sort of verification (license?) tool:
http://jigsaw.w3.org/css-validator/check/referer
http://validator.w3.org/check?uri=referer
I've stated a couple of times that I'm not really a tech guy, so I actually don't know what these 2 are supposed to verify, but the thing is none of them is actually working? They are working in a sense that the website loads, but one sends a forbidden error back, and the second one brings a "Sorry! This document cannot be checked." I also tried searching by url on that one, as it is suggested on the tab that is opened, and bitcointalk.org-->
2 Errors, 1 warning(s) So my question are as follows:
-What are these 2 guys?
-What are they supposed to validate?
-If they are not working or outdated, why are they there?
